Patients should use OMNARIS Nasal Spray at regular intervals since its effectiveness depends on its regular use. In clinical trials, the onset of effect was seen within 24 to 48 hours with further symptomatic improvement observed over 1 to 2 weeks in seasonal allergic rhinitis and 5 weeks in perennial allergic rhinitis. Initial assessment of response should be made during this time frame and periodically until the patient's symptoms are stabilized. The patient should take the medication as directed and should not exceed the prescribed dosage. The patient should contact the physician if symptoms do not improve by a reasonable time or if the condition worsens.
Steroids are naturally-occurring hormones that are produced by the adrenal glands. The corticosteroids have potent anti-inflammatory effects and are very effective in treating allergic inflammation in the nose. They are a "controller" type medication and work best when used on a regular "preventative" basis. They are usually only available by prescription. With seasonal allergies, daily use of these sprays should begin 1 to 2 weeks before the allergy season and continue throughout the season. In people with relatively constant or perennial allergic rhinitis, particularly if symptoms have been unresponsive to OTC or other treatments, daily use of intranasal steroids has been found very effective in controlling symptoms, particularly nasal congestion. The addition of antihistamines to this nasal spray will likely give even better results.
Steroid nasal sprays rarely cause side-effects. This is because they are applied directly to the nose and very little of this medicine is absorbed into the body. Therefore, they are much less likely to cause side-effects in other parts of the body. Occasionally, they cause dryness, crusting, and bleeding of the nose. If this occurs, stop it for a few days and then restart. There have been reports of nasal steroids possibly having an effect on behaviour, particularly in children. This is thought to be rare. However, a few people have reported hyperactivity, problems sleeping, anxiety, depression, and aggression.
